I assume you agree that you should still back then up and that it doesn't have to be to SSD.
using ssd does not mean no backups.
But you've calimed they are more relible, there's as yet not enough evidence to claim that.Whisky-davenospam
I doubt the cloud is entirley made up of SSDs, there's a reason for that.
ssd would be a waste for the cloud, as any speed advantage would be wasted.
In theory and as yet unproven.Whisky-dave
I'm really not sure which would be the most *relible* a SSD of around 512Gb or spending that amount of cash on 512Gb HDDs and keeping clones as backups.The good SSDs have similar life spans to HDDs.nospam
actually much better than hd.
No it can;t it's the technology behind it.Whisky-davenospam
they aren't quite as good with updating data in small files especailly as the disk becomes full, SSDs can't overwrite existing data,
of course it can.
copy new files to it and whatever was there before is overwritten. it's that simple.No it's not.
to the host, whatever you mean by thay, but it takes extra time and resources.Whisky-davenospam
what it does is when needed it has to erase data before writng the changes, it has to copy the file to another location first.
so what? that's done internally and transparent to the host.
It is that's why they are developing new types of SSD and even currebntly they are diffent types. http://www.kingston.com/en/ssdWhisky-davenospam
Although I wouldn;t say it a major problme for most unless they fill thier SSD. Hopefully the new FRAM SSDs will overcome is.
it's not a problem at all.
you've not heard of DVD cleaners ? Shows you how little you know about the subject.Whisky-davenospam
Re-writables then to home burnt ones because they refelct less laser light than commerial CD/DVDs as they have a refective coating added. Could be iimportent if you back-up to such media.
it's a non-issue, since all optical drives made in the last 20 years or so can read writeable discs.
Yes it does, just like records or even words on paper.nospamhowever, dropping or improper handling can scratch it but that doesn't usually matter much since the data is below the surface and any scratches make very little difference unless they're fairly big. a little scuffing is not going to cause data loss.Whisky-dave
depends on the direction of the scuff also.
no
then stop using the word LOST becaus eit has no meaning here.Whisky-davenospam
I've never lost my house keys, but I;ve needed to use my duplcate set. My keys were inside the house, but I needed my backup.
irrelevant comparison.
and you don't loss data it becomes corrupted and that is what people say they have lost data.Whisky-davenospam
I'm sure we've all lost something and had someone tells us no you left you're lens cap here or I picked up your lighter, it was on teh floor sort of thing.
you don't leave your data on the couch.
You've got no idea have you.nospamWhisky-daveWhisky-davenospam
If a file can't be found does that mean it's moved or deleted.
who cares why.
it does to backup software.
no it doesn't.
Then person that want to recover the data, or the person that made a backup.nospamif it can't be found, it's lost.Whisky-dave
Maybe it can be resued but only opened as a RTF or texfile. perhaps only the data fork is found and not the resourse fork. Or perhasp on the PC a .doc has been change to a .jpg
who cares.
if there's *any* problem with the original, you get a backup copy.But you have to know there's a problem.
No it does not. I guess you've never come across the LOST+FOUND directory have you. http://unix.stackexchange.com/questions/18154/what-is-the-purpose-of-the-lostfound-folder-in-linux-and-unixWhisky-davenospam
With the word LOST in computer terms it measn it's not where it expects the file to be.
lost means the data is gone.
ONLY yes the file still exists.nospamWhisky-daveWhisky-davenospam
Even when you delete a file all that happens is that data is changed no data is lost useful information might derived from the file.
if you delete a file, it's gone.
No it's not, all that happens is the start and end locations amonst others of the file are 'zeroed out' for the want of a better word , thats how some recovery programs work.
actually what happens is the directory entry is changed.
the file data itself is still there, but none of that matters. as far as the user is concerned, the file is gone and they need to get a backup copy.That's how recovery programs work, because the file has NOT gone. You can auctually still see the data using disc editing tools.
a recovery app can get at the old data, assuming it hasn't been overwritten by *another* file, which it often is by the time the user realizes the file is gone,that's what I mean in that you have to knbow the file is gone to know you have lost it.
but why bother with all that when you can easily pull the file off a backup.That's why you keep backups for when things do go wrong, which can happen on any sort of media whether it be user error or a system failure or even theft. But in all of these you jhave to know you are missing something before you bother goinf to recover it.
